Researchers Develop Novel Polyploid Breeding Method for Kelp
The research team from IOCAS has successfully developed new technique for kelp polyploid breeding. Saccharina japonica and Undaria pinnatifida are the two most commercially important kelps in the world. However, continuous rising seawater temperatures and more frequent marine heatwaves are increasingly threatening the kelp cultivation industry, makin...

Researchers Develop Wave-driven Tubular Platform for Corrosion Protection and Environmental Sensing
Researchers from IOCAS have developed a wave-driven tubular platform based on dynamic multi-interface electrical double layers. Marine equipment faces persistent risks from coating damage and metal corrosion, while monitoring and protection systems require reliable power supplies and regular maintenance. Harnessing wave energy offers a renewable energy source, but integrating po...

Study Reveals Important Role of Deep Mantle Upwelling in Driving Back-Arc Spreading
A research team from IOCAS has made a three-dimensional (3-D) P-wave tomographic study of the Izu-Bonin-Mariana (IBM) subduction zone.Subduction zones are among the most important sites for material circulation between Earth's surface and interior. Arc rupture and back arc expansion reflect the complex interactions between deep processes and surface structures on Earth, playing an imp...

Study Reveals How Deep-sea Methanogens Thrive in Phosphorus-Starved Environments
A research team from IOCAS has revealed that deep-sea methanogenic archaea efficiently utilize phosphorus and store energy through polyphosphate (polyP) metabolism.In deep-sea ecosystems, methanogenic archaea are key drivers of the global methane cycle, particularly in methane-rich cold seep environments. Phosphorus, an essential element for life, is typically utilized by microorganisms as inorganic phosphate. In ...

Study Reveals Hidden Role of Phytoplankton in Multi-Year La Niña Evolution
A research team from IOCAS has found that phytoplankton-induced radiation effects reshape the evolution of multi-year La Niña.La Niña—persistent abnormal cooling of sea surface temperatures (SST) in the central-eastern tropical Pacific—has profound global climate impacts. When such an event lasts more than two years (multi-year La Niña), its effects intensify. In recent de...

Scientists Discover Key Role of Ocean Salinity in Improving ENSO Forecasts
A research team from IOCAS investigated the role of ocean salinity using observational data and an interpretable artificial intelligence framework (STPNet). The El Niño–Southern Oscillation (ENSO) is one of the most influential climate phenomena on Earth, shaping weather patterns worldwide and driving extreme events. For decades, scientists have relied primarily on sea surface temperature to predict ENSO....

Study Uncovers Pervasive Endogenous Viral Elements in Crustaceans
A research team from IOCAS, alongside collaborators from Thailand provided new insights into dynamic viral endogenization in crustaceans.Endogenous viral elements (EVEs), known as molecular fossils of ancient viral infections, are viral genetic fragments integrated into host genomes and transmissible across generations, providing a unique perspective for studying the evolutionary arms ra...

Researchers Discover Seamounts Promote Expansion of Oxygen Minimum Zone in Western Pacific
The research team from IOCAS found that seamount promoted the expansion of the Oxygen Minimum Zone to a certain extent.Seamounts and the Oxygen Minimum Zone (OMZ) are two typical habitats that often co-exist in the deep ocean. However, it remains unexplored and unverified whether the 'seamount effect' alters OMZ structure based on marine stratification, thus impacting d...
